DRIERt Application tiled April 23, 1923. Serial No. 633,842.

To all Hr/71077@ 'if may concern.' i

Be it known that I,- GIovANNI CAPPEL- Liirrr. a citizen of the United States,`re

siding at San Francisco. in theV county of San Francisco, State of California, have invented a new and useful Drier, of which the following is a specification in such full and clear terms as will enable those skilled in the art to 'Construct and use the same.

This invention relates to drier for cereal pastes, such as macaroni, spaghetti and the like, and is particularly adapted for drying short lengths of macaroni, and one of the objects of the invention is to provide a uniform circulation of air through the macaroni.

Another object of the invention is to provide screens inclosing the macaroni while drying and means for readily cleaning the Z0 screens. y

Another object is to provide a drier that can be filled or emptied quickly.

Another object is to provide means for circulating air through the macaroni first 35 in one direction, then in another.

Another object is the use of screens in the diffusion of air through the drier.

Vihile this machine is especially adapted to dry macaroni it is evident that it may be used to dry a considerable number of other products such as vegetables, meat and other products containing an excess of moisture.

@ther objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modications thereof.

Fig. 1 is a front elevation of the drier,

Fig. 2 is a side elevation looking from the left of Fig. 1,

Fig. 3 isa side elevation looking 'from the right of Fig. l,

Fig. 4; is a longitudinal vertical section of the drier,

Fig. 5 is a plan of one of the trays,

Fig. 6 is a section of one of the trays,

Fig. 7 is a section of one of the top and 50 bottom enclosing screens.

Fig. 8 is a sectional view of a modified form of drier.

The numeral 1 indicates a floor of the drier, which, in this instance, is the floor of the room in which the drier is located.

The drying chamber is `formed by thel side walls 2 and`3, the vfront wall t, land theback wall .5. The end wall 2 has a door 6, and the wall v3 has the door 7. The doors are provided kwith suitablev hinges 3 and latches 9.

At the .bottom of the -walls`2 and 3 there is an opening 10in which is pivoted a slat 11 adapted to close the opening or partially open same, a screen 12 covers this opening at the back.

The drier is divided into two drying chambers A and B, by the partition 13 which may be hollow, as shown, or solid. Horizontal guide strips 14; are fixed to the vertical posts 15 to receivey sliding trays 16. Screens 17 are provided to cover the bottom of vdrying chambers A and B, and a similar screen 2O is provided to cover the tops of the chambers. These screens are readily removable, anv enlarged section of the screen and frame is shown in Fig. 7.

Through the partition 13 is an opening 2l in which is mounted a blower 22 on the shaft 23, a bearing 24 supported by bracket 25, and a bearing 26 supported by the-crossspacing the screen from the bottom; a cross-l bar 32 serves to strengthen the frame. A handle 33 is provided to pull the tray in or out.

The screen 17 and 2O has a frame ,34: to i.

which the screen is attached. Openings 34;

in the drier, then the blower is started and f run at a speed to give a predetermined flow of air in the direction shown by the arrows, or in opposite direction when the blower reversed.

The airis drawn down throughthe screens 20 and through the macaroni, and the screen 30 in the bottomof trays through ithewscreens 17, through the blower andi up through screens 17 in the other chamber, and up through tray screens and .macaroni and out.

through screens 20.

In the modiedform of drier shownie- F ig. 8 space is left at the top of the drying chambers, vand a blower placed therein which in effect is the same as turning the above described drier up side down, ex:- cept that space should be allowed under the-trays as shown:y The dryinglchambers C andv D are divided byth'e partition which a blower 36 is mounted. Screens 37 and'. 38 inclose'V the chambers, 39 are thel trays, andi-40 representthe space'under 'the tra-ys'.

tions may be made in carrying out vtlrerirr; ventionf shown iny the 'drawings and in Athe What Ifclaim is as follows butiniodiica'-A above particularly described forni thereof, within the.: purview ofv the invention Ina drier of the class describedQau enclosure forming `a pair of drying chambers,

a. fan locatedin an .opening in the partition between said two chambers to cause air to passfrom one of said chambers tothe other,

screen bottom trays in both of said cham-- bers, whereby. the air `will passdownwardly ,f through certain` 'of vsaid trays to the ian and upwardly through the'other trays from the fan.

In testimony whereof I have hereunto set' my hand Vthis 30th' day of-March A. DL '1923.
